Cavitt Old Dominion University, 2000 Director: Dr. C. Michael Overstreet Technology advances are providing greater capabilities for most distributed computing environments. However, the advances in capabilities are paralleled by progressively increasing amounts of system complexity. In many instances, this complexity can lead to a lack of understanding regarding bottlenecks in run-time performance of distributed applications. This is especially true in the domain of distributed simulations where a myriad of enabling technologies are used as building blocks to provide large-scale, geographically disperse, dynamic virtual worlds. Persons responsible for the design, configuration, and control of distributed simulations need to understand the impact of decisions made regarding the allocation and use of the logical and physical resources that comprise a distributed simulation environment and how they effect run-time performance. Distributed Interactive Simulation (DIS) and High Level Architecture (HLA) simulation applications historically provide some of the most demanding distributed computing environments in terms of performance, and as such have a justified need for performance information sufficient to support decision-makers trying to improve system behavior. This research addresses two fundamental questions: 1) Is there an analysis framework suitable for characterizing DIS and HLA simulation performance? and 2) what kind of mechanism can be used to adequately monitor, measure, and collect performance data to support different performance analysis objectives for DIS and HLA simulations? This thesis presents a unified, architectural framework for DIS and HLA simulations, provides details on a performance monitoring system, and shows its effectiveness through a series of use cases that include Reproduced with permission of the copyright owner.

    1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system.

  • Status of High Level Architecture Real Time Platform Reference Federation
    STATUS OF HIGH LEVEL ARCHITECTURE REAL TIME PLATFORM REFERENCE FEDERATION OBJECT MODEL (RPR FOM) Peter Ryan1, Peter Ross1, Will Oliver1, and Lucien Zalcman2 1Air Operations Division, Defence Science & Technology Organisation (DSTO), 506 Lorimer St, Fishermans Bend, Melbourne, Victoria 3001. Email: [email protected] 2Zalcman Consulting. Email [email protected] ABSTRACT Several advanced distributed simulation architectures and protocols are currently in use to provide simulation interoperability among Live, Virtual, and Constructive (LVC) simulation systems. Distributed Interactive Simulation (DIS) and High Level Architecture (HLA) are the most commonly used protocols/architectures in the simulation community. HLA is a general purpose architecture for distributed computer simulation systems. To enable HLA federates to interoperate with DIS systems, the Real Time Platform Reference Federation Object Model (RPR FOM) was developed. The RPR FOM defines HLA classes, attributes and parameters that are appropriate for real-time, platform-level simulations. This paper provides a discussion of the current interoperability standards, an update on the status of the RPR FOM, and the implications for Australia. 1. INTRODUCTION Advanced Distributed Simulation (ADS) protocols and architectures were created so that various Live-Virtual- Constructive (LVC) systems could interoperate with each other in a simulated game or exercise in the same synthetic battlespace [1]. The simulation nodes may be collocated or may be geographically remote from each other. Interoperability among such LVC systems can be improved using a specifically designed set of predefined interoperability standards. Such predefined sets of interoperability standards are commonly referred to as Modelling and Simulation Standards Profiles (such as the NATO Modelling and Simulation Standards Profile [2]).

University of Cape Town ABSTRACT MURAC: A unified machine model for heterogeneous computers by Brandon Kyle Hamilton February 2015 Heterogeneous computing enables the performance and energy advantages of multiple distinct processing architectures to be efficiently exploited within a single machine. These systems are capable of delivering large performance increases by matching the applications to architectures that are most suited to them. The Multiple Runtime- reconfigurable Architecture Computer (MURAC) model has been proposed to tackle the problems commonly found in the design and usage of these machines. This model presents a system-level approach that creates a clear separation of concerns between the system implementer and the application developer. The three key concepts that make up the MURAC model are a unified machine model, a unified instruction stream and a unified memory space. A simple programming model built upon these abstractions provides a consistent interface for interacting with the underlying machine to the user application.

  • Gate-Level Leakage Assessment and Mitigation
    Gate-level Leakage Assessment and Mitigation Tarun Kathuria Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Computer Engineering Patrick R. Schaumont, Chair Cameron D. Patterson Xun Jian June 26, 2019 Blacksburg, Virginia Keywords: Side-channel leakage, Countermeasures, Power analysis attacks Copyright 2019, Tarun Kathuria Gate-level Leakage Assessment and Mitigation Tarun Kathuria (ABSTRACT) Side-channel leakage, caused by imperfect implementation of cryptographic algorithms in hardware, has become a serious security threat for connected devices that generate and process sensitive data. This side-channel leakage can divulge secret information in the form of power consumption or electromagnetic emissions. The side-channel leakage of a crytographic device is commonly assessed after tape-out on a physical prototype. This thesis presents a methodology called Gate-level Leakage Assessment (GLA), which evaluates the power-based side-channel leakage of an integrated circuit at design time. By combining side-channel leakage assessment with power simulations on the gate-level netlist, GLA is able to pinpoint the leakiest cells in the netlist in addition to assessing the overall side-channel vulnerability to side-channel leakage. As the power traces obtained from power simulations are noiseless, GLA is able to precisely locate the sources of side-channel leakage with fewer measurements than on a physical prototype. The thesis applies the methodology on the design of a encryption co-processor to analyze sources of side-channel leakage. Once the gate-level leakage sources are identified, this thesis presents a logic level replacement strategy for the leakage sources that can thwart side-channel leakage.

  • Integrating E Verification IP in a VMM Testbench
    Integrating e Verification IP in a VMM Testbench JL Gray Verilab [email protected] Adiel Khan Synopsys [email protected] 30 March 2010 ABSTRACT Modern testbenches often consist of components drawn from multiple languages. In many of these cases, multi-language and multi-methodology interaction is not well defined. In this paper, we will demonstrate the use of e verification components (eVCs) in a SystemVerilog/VMM testbench. Several complex issues arise when using SystemVerilog as the “primary” language. Initial simulator engine synchronization, random generation ordering, timing problems caused by program blocks, and methodology synchronization between the VMM and eRM will all be discussed.

  • Model-Driven Distributed Simulation Engineering
    Proceedings of the 2019 Winter Simulation Conference N. Mustafee, K.-H.G. Bae, S. Lazarova-Molnar, M. Rabe, C. Szabo, P. Haas, and Y.-J. Son, eds. MODEL-DRIVEN DISTRIBUTED SIMULATION ENGINEERING Paolo Bocciarelli Andrea D’Ambrogio Andrea Giglio Emiliano Paglia Department of Enterprise Engineering University of Rome Tor Vergata Rome, Italy ABSTRACT Simulation-based analysis is widely recognized as an effective technique to support verification and validation of complex systems throughout their lifecycle. The inherently distributed nature of complex systems makes the use of distributed simulation approaches a natural fit. However, the development of a distributed simulation is by itself a challenging task in terms of effort and required know-how. This tutorial introduces an approach that applies highly automated model-driven engineering principles and standards to ease the development of distributed simulations. The proposed approach is framed around the development process defined by the DSEEP (Distributed Simulation Engineering and Execution Process) standard, as applied to distributed simulations based on the HLA (High Level Architecture), and is focused on a chain of automated model transformations. A case study is used in the tutorial to illustrate an example application of the proposed model-driven approach to the development of an HLA-based distributed simulation of a space system. 1 INTRODUCTION The development of complex systems strongly benefits from the adoption of quantitative analysis techniques that enable an early evaluation of the system behavior, so to assess, before starting implementation or maintenance activities, whether or not the to-be system is going to satisfy the stakeholder requirements and constraints. In this context, simulation-based techniques may be effectively introduced to enact the design-time evaluation of various structural and/or behavioral properties of the system under study.

    Software Maintenance Maturity Model (SMmm): The software maintenance process model Alain April1, Jane Huffman Hayes* ,†,2, Alain Abran1, and Reiner Dumke3 1Department of Software Engineering, Université du Québec, École de Technologie Supérieure, Canada 2Department of Computer Science, University of Kentucky, U.S.A. 3Department of Informatik, Otto von Guericke Universtity of Magdeburg, Germany. SUMMARY We address the assessment and improvement of the software maintenance function by proposing improvements to the software maintenance standards and introducing a proposed maturity model for daily software maintenance activities: Software Maintenance Maturity Model (SMmm). The software maintenance function suffers from a scarcity of management models to facilitate its evaluation, management, and continuous improvement. The SMmm addresses the unique activities of software maintenance while preserving a structure similar to that of the CMMi©4 maturity model. It is designed to be used as a complement to this model. The SMmm is based on practitioners’ experience, international standards, and the seminal literature on software maintenance. We present the model’s purpose, scope, foundation, and architecture, followed by its initial validation. Copyright © 2004 John Wiley & Sons, Ltd. J. Softw. Maint.
